 Chair-philosophy is burdened with the disadvantage which philosophy as a profession imposes on philosophy as the free investigation of truth, or which philosophy by government order imposes on philosophy in the name of nature and mankind.Sämtliche Werke, Bd. 5, p. 151, E. Payne, trans. (1974) Vol. 1, p. 139

 A government will not pay people to contradict directly, or even only indirectly, what it has had promulgated from all the pulpits by thousands of its appointed priests or religious teachers. … Hence the maxim improbant secus docentes [We reject and condemn the man who teaches something different].Sämtliche Werke, Bd. 5, pp. 152–153, E. Payne, trans. (1974) Vol. 1, p. 139
